Description
Anhydrous copper chloride has dark yellow crystals that absorb water to form green deliquescent crystals. Copper chloride is used as a disinfectant, fungicide, and wood preservative. It is also used as a fixer in photography, a mordant in dyeing textiles and a component in indelible inks. In metallurgy, copper chloride is used refine gold and silver, to recover mercury from ore, and to electroplate copper on aluminum. Copper chloride is also used as a glass and ceramics pigment.
